Association between the mode of transport and in-hospital medical complications in trauma patients: findings from a level-I trauma center in Saudi Arabia.

BACKGROUND: In Saudi Arabia, injury is the leading cause of death. Even if nonfatal, the impact of injuries on population health is enormous, as thousands of young patients suffer permanent disabilities every year. Unlike in developed countries, private transportation (PT) is a common means to transport trauma patients. Outcome differences between patients transported via PT relative to emergency medical services (EMS) has not been previously explored.

OBJECTIVES: To evaluate the association between transportation mode and in-hospital complications among trauma patients.

DESIGN: Retrospective.

SETTING: Tertiary care center.

PATIENTS AND METHODS: The study included all patients (>=16 years), who were admitted following trauma.

MAIN OUTCOME MEASURES: The main outcome in the study was the occurrence of any medical complications including stroke, sepsis, myocardial infarction, pulmonary embolism, pneumonia, renal failure, acute respiratory distress syndrome, and cardiac arrest.

RESULTS: The 493 patients were relatively young (over two-thirds of the sample were 45 years old or younger) and over half the population sustained injuries due traffic crashes. More than half (58%) of patients arrived via private transportation. Regression analyses revealed that in-hospital complications following injuries were significantly lower among those who arrived via PT. However, after incorporating propensity score matching, we found no difference in hospital complications (OR=0.55, 95% CI 0.25-1.17).

CONCLUSION: Multiple factors may influence this unexpected finding, such as distance to health care set.tings, the belief that PT is faster or lack of knowledge of the EMS contact number. Further efforts are needed to raise awareness of the importance of using EMS to transport trauma patients to hospitals. Prevention programs to reduce traffic crashes may facilitate reduction in traumatic injuries and associated complications.

LIMITATIONS: Retrospective and conducted in one center only.
